JOHN POHLSEN, OF NEWARK, NEW JERSEY.

LIGHT-EXTINGUISHER FOR LAMPS.

SPECIFICATION forming part of Letters Patent No. 280,511, dated July 3,1883,

' Application filed January 8, 1883. (No model.)

tion, such as will enable others skilled'in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to letters of reference marked thereon, whichform a part of this specification.

The object of this invention is to improve the construction and perfectthe operation of light-extinguishers for lamps; and it consists in thearrangements and combinations of parts, substantially as will behereinafter set forth, and finally embodied in the claim.

Referring to the accompanying drawings, in which the several letters ofreference indicate like parts in each of the several figures, Figure 1is a plan View of my improved device, the burner-cap being removed toshow the construction beneath, and, further, showing the extinguishingsemi-caps closed together over the wick. Fig. 2 is a side elevation,showing the extinguishing semi-caps apart. Fig. 3 is a portional sideelevation. Fig. 4. is a sectional view of an extinguishing semi-caphaving arms by which the same is pivoted to a plate arranged over thewicktube, and Fig. 5 is aplan of said plate disconnected from theremainder of the burner.

In carrying out my invention I construct a burner in the ordinary way, ain the drawings being the bed of the burner; b, the cap arrangedthereon, having the usual opening or slot, 0, therein, through which theflame passes, and (I being the wick-containing tube.

Over or around the wick-tube is placed the fulcrumal and pivotal platee, having a slot, f, therein conforming in'shape to the wicktube, sothat when said plate is placed upon said tube no riveting, soldering, orother means are required to hold the said plate in position. Theextremities of the plate are provided with pivotal projections 9,adapted to receive the arms of the semi-caps.

Upon the plate e are arranged the semicaps h, having the arms Q3projecting downward from each side of the cap and pivoted upon theprojections 51. One of said arms on each semi-cap is extended downwardfrom said pivotal point, forming a finger-piece, 0, by which thesemi-cap is brought over the wick to extinguish the flame, inconjunction with the opposite semi-cap, all as will be understood. Thelower edges of the semi-caps are approximately on a line with the top ofthe wick-tube, so that the said caps do not offer any obstruction to theair coming through the perforated base a.

To cause the semi-caps to separate automatically, I arrange aspring-wire, 12, around the wick-tube at a little distance therefrom, asshown, and secure the ends thereof by thrusting them through aperforation in one arm in each cap, so that the tendency of the springwill be to cause the arms to separate. The spring-wire, passing underthe plate 0 at a point opposite to where the ends are secure, is helddown in place thereby. The fingerpieces 0 pass downward through theperforated bed a, and are bent outward, as shown, so that they may bemanipulated with the greatest convenience.

The parts thus described can be arranged together with the, greatestfacility and ease, without any riveting, soldering, or other similarlytedious process, by simply springing the same together, where they willremain without liability to become disengaged. The parts It i 0 arestamped up in one integral piece of sheet metal.

The device as a whole can be constructed at a very small cost, iseffective in its operations, will not interfere with the flame, and isnot liable to get out of order.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

The combination, with the base a, cap I), and wick-tube d, of theperforated plate 6, having pivotal projections g thereon, pivotedsemi-caps h, closing finger-pieces projecting through the said base a,and the spring, all said parts being arranged and operating substantially as herein set forth and shown.

I11 testimony that I claim the foregoing I have hereunto set my handthis 26th day of December, 1882.

JOHN POHLSEN.
